管理擴展ApplicationUser

Question

使用ASP.NET 5 Web應用程序模板，並通過增加BUSINESSNAME

public class ApplicationUser : IdentityUser 
{ 
    public string BusinessName { get; set; } 

中的DbContext的BUSINESSNAME屬性擴展ApplicationUser

public partial class CustomersContext : IdentityDbContext<ApplicationUser> 
{ 
    protected override void OnModelCreating(ModelBuilder modelBuilder) 
    { 
     base.OnModelCreating(modelBuilder); 
     modelBuilder.Entity<ApplicationUser>(entity => 
     { 
      entity.HasIndex(e => e.BusinessName).HasName("BusinessNameIndex"); 

      entity.Property(e => e.BusinessName) 
       .HasMaxLength(255) 
       .HasColumnType("varchar"); 

BUSINESSNAME也被添加到的ViewModels /管理/ IndexViewModel.cs

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Threading.Tasks; 
using Microsoft.AspNet.Identity; 

namespace Customers.Web.ViewModels.Manage 
{ 
    public class IndexViewModel 
    { 
     public bool HasPassword { get; set; } 

     public IList<UserLoginInfo> Logins { get; set; } 

     public string BusinessName { get; set; } 

     public string PhoneNumber { get; set; } 

     public bool TwoFactor { get; set; } 

     public bool BrowserRemembered { get; set; } 
    } 
} 

ManageController指數動作稱爲

 public async Task<IActionResult> Index(ManageMessageId? message = null) 
    { 
     ViewData["StatusMessage"] = 
      message == ManageMessageId.ChangePasswordSuccess ? "Your password has been changed." 
      : message == ManageMessageId.SetPasswordSuccess ? "Your password has been set." 
      : message == ManageMessageId.SetTwoFactorSuccess ? "Your two-factor authentication provider has been set." 
      : message == ManageMessageId.Error ? "An error has occurred." 
      : message == ManageMessageId.AddPhoneSuccess ? "Your phone number was added." 
      : message == ManageMessageId.RemovePhoneSuccess ? "Your phone number was removed." 
      : ""; 

     var user = await GetCurrentUserAsync(); 
     var model = new IndexViewModel 
     { 
      HasPassword = await _userManager.HasPasswordAsync(user), 
      PhoneNumber = await _userManager.GetPhoneNumberAsync(user), 
      TwoFactor = await _userManager.GetTwoFactorEnabledAsync(user), 
      Logins = await _userManager.GetLoginsAsync(user), 
      BrowserRemembered = await _signInManager.IsTwoFactorClientRememberedAsync(user) 
     }; 
     return View(model); 
    } 

同時也查看/管理/ Index.cshml

@model IndexViewModel 
@{ 
    ViewData["Title"] = "Manage your account"; 
} 

<h2>@ViewData["Title"].</h2> 
<p class="text-success">@ViewData["StatusMessage"]</p> 
<div> 
    <h4>Change your account settings</h4> 
    <hr /> 
    <dl class="dl-horizontal"> 
     <dt>External Logins:</dt> 
     <dd> 
      @Model.Logins.Count [<a asp-controller="Manage" asp-action="ManageLogins">Manage</a>] 
     </dd> 

     <dt>Business Name:</dt> 
     <dd> 
      @Model.BusinessName 
     </dd> 

什麼是填充BUSINESSNAME正確的方法是什麼？

Answer 1

在你的控制器動作，您沒有設置BusinessName您的視圖模型：

var user = await GetCurrentUserAsync(); 
var model = new IndexViewModel 
{ 
    BusinessName = user.BusinessName, 
    ... 
};
